Definitions

  • the present invention relates to a transport and/or storage container for radioactive elements. More particularly this invention concerns such a container used to ship fresh or used fuel rods or high-active-waste glass units.
  • a typical storage/transport container for radioactive elements is basically formed as a massive barrel, typically of reinforced concrete, having a flat circular floor, a cylindrical side wall extending upward from the floor, and a flat circular cover that fits on the upper rim of the side wall so as to define a cylindrical interior. Since the elements placed in such a container can be of different lengths, since they expand and contract somewhat because of radioactive-decay heating, and also since the container is not made to extremely tight tolerances, it is standard to make the interior somewhat taller than the longest element that is likely to be stored in the container. This leaves under normal circumstances, that is when the container is standing on its floor with its cover up, an empty free space above the elements and below the cover.
  • Another object is the provision of such an improved transport/storage container for radioactive elements which overcomes the above-given disadvantages, that is which can better resist breakage if it is dropped on its cover.
  • a storage/transport container comprising a floor, a side wall, and a cover fittable with the side wall to form with the floor and side wall a closed interior having a height between an inner face of the floor and an inner face of the cover that is greater than an overall length of the element.
  • a spring is engaged between a lower end of the rod and the floor and has a spring force smaller than a weight of the rod so that when the cover is above the floor an upper end of the rod is spaced below the cover and when the floor is above the cover the spring presses the rod upper end against the cover.
  • the element is a fuel rod.
  • the container is designed to hold a plurality of the elements, each with its own spring so that elements of different length can be accommodated.
  • the spring in accordance with the invention is a simple coil compression spring. It can be at least partially received in a pocket formed in a lower end of the rod so that the system of this invention can be used with a conventional transport/storage container. Typically the pocket is deep enough to completely contain the spring in compressed condition so that, under normal circumstances, the element sits directly on the floor of the container. Each element is formed with such a pocket for its spring.
  • FIG. 1 is a partial axial section through a container according to the invention as it is being loaded
  • FIG. 2 is a view like FIG. 1 showing the loaded and closed container
  • FIG. 3 is a view like FIG. 2 but showing the container inverted.
  • a standard container according to the invention is centered on a normally vertical axis A and has a flat horizontal floor 3 , a cylindrically tubular side wall 4 , and, when complete, a flat horizontal cover 5 together defining a cylindrical interior 1 having a height H.
  • a container is typically loaded with radioactive fuel elements, here spent fuel rods 2 of which one is shown.
  • the rod 2 has an overall length h which is shorter than the height H by a distance f so that, when sitting on the floor 3 , there is a space between its upper end and the cover 5 as shown in FIG. 2 .
  • the cover 5 here is shown as one piece although it is often constituted as two separate disks that may even be separated by a slight spacing.
  • the lower end of the rod 2 is formed with a blind cylindrical pocket 7 in which is seated a steel coil-compression spring 6 , although it is within the scope of the invention to use an elastomeric spring element.
  • the pocket 7 is of rounded cup-shaped.
  • this spring 6 has an overall length L that is substantially more than the distance f. The strength of this spring 6 is, however, such that the weight of the rod 2 is sufficient to compress it by an amount V until it is completely contained in the pocket 7 and the rod 2 sits with its lower end directly on the floor 3 .
  • the spring 6 is prestressed.
